Kay: what do you think about will? Caroline: he's cute. why? Kay: well we're gonna hookup. Caroline: what? omfg don't do it! no! Kay: okayy i won't.... cockswatter! (She then hooks up with the boy, ignoring her friend's useless cockswatting.)
n. software that is no longer sold or supported by the original publisher / developer, often found as free downloads on the internet because it cannot be obtained elsewhere. Not legal, but often seen as morally acceptable because the company that made it is no longer selling the title, nor releasing it as freeware, therefore abandonware is "keeping the gamealive", so to speak.
Doom II is not abandonware because idstill sells it, while The Incredible Machine is not sold, therefore is abandonware.
